dB → V → P ratio tool

The equation below shows the relationship between a decibel value and a linear voltage/power ratio. This calculator is can be used in one of three ways:

  • A decibel value can be specified and the linear voltage and power ratios will be returned
  • A linear voltage ratio can be specified and the decibel value together with the linear power ratio is returned
  • A linear power ratio can be specified and the decibel value together with the linear voltage ratio is returned
